A guest is dead and one of you did it. The AI host reveals clues round by round; you interrogate each other in your own words, watch for slips, then make your accusation. Catch the killer — or, if it's you, get away with it.
Unlike boxed murder-mystery kits, there's nothing to print and no script to read: the AI runs the case and reacts to what your group actually says. Every game is a different evening.
A game suits 3 to 10 players and runs about 20–30 minutes as clues unlock round by round. Because the AI generates a fresh case each time — victim, motive, and culprit — it's endlessly replayable, unlike a boxed kit you can only solve once. Everyone joins from a phone with a room code, so it works for a dinner party in one room or a group spread across a video call.
4–10 players · AI-hosted · plays in the browser, no app.
How to play
One of you is the secret killer; everyone else is an innocent guest with their own backstory (tap your secret card to re-read it).
Each round the AI host reveals new clues.
Interrogate each other in your own words when prompted — question, defend, deflect.
At the end everyone accuses someone. Innocents win by catching the killer; the killer wins by getting away with it.
Frequently asked questions
Do we need to prepare anything, like a murder mystery dinner kit?
Nothing. Pick the game, share the room code, and the AI generates the case, the clues, and the reveal. Zero printing, zero prep.
Can we play the same murder mystery more than once?
Every game is a new case — different victim, clues, and culprit — so it never spoils. That's the main advantage over a one-time boxed mystery kit.
How many players does Murder Mystery support?
Murder Mystery plays with 4 to 10 players. Everyone joins from their own phone or laptop browser with a 4-letter room code.
Do I need to download an app or own a console?
No — it runs entirely in the browser. The host starts a room on aipartygames.com, players open the link, and the AI hosts the game.
